Application January 22, 1934, Serial No. 797,870

provide a quickly detachable coupling whereby a portable sprinkler head may be readily attached to any of a plurality of spaced valved 10 water outlets whose upper ends are flush with the surface area to be watered; to provide such a coupling whose portable sprinkler head is provided with a manually controlled lever for operating the normally closed valve of the fixed 15 water outlet; to provide a coupling having a fixed water outlet provided with a swingable cover for protecting the water outlet and its valve which when in its closed position is flush with the surface area; to provide a valved water outlet whose 20 valve cannot be opened except by a manually controlled lever associated with the sprinkler head when the sprinkler head is detachably secured to its fixed water outlet; and, to provide a quickly detachable coupling of the character 25 above indicated which is simple in construction,

economical in manufacture and eflicient in use.

An illustrative embodiment of the invention is shown in the accompanying drawings. wherein:

Figure 1 is an elevational view 01 the valved coupling;

Figure 2 is an elevational view of the valved water outlet portion of the coupling, showing its swingable cover in closed position and flush with the surface area when not in use;

Figure 3 is a perspective view of the valved water outlet portion of the coupling showing its swingable cover in open position and ready to detachably receive the sprinkler head portion of the coupling;

Figure 4 is a perspective view of the under- I ground water supply system and its several valved water outlets flush with 'the surface area to be watered, a conventional type sprinkler head being shown for detachable connection with any of 5 the several water outlets;

Figure 5 is a sectional view on line 5-5 of Figure 6;

Figure 6 is a central longitudinal sectional view on line 6-5 of Figure 7 but showing the manu- 50 ally operated lever controlled cam out of valve opening position;

Figure '7 is a sectional view on line 7-! of Figure 6 but showing the manually operated lever controlled cam depressing the valve plunger to w valve opening position; and

Figure 8 is a i entary sectional view of the valved water outlet and its swinging cover in closed position.

Referring to the drawings in which like s of the structure shown are designated by the 5 same numerals in the several views, the sprinkler head coupling generally comprises a tubular water outlet it adapted for vertical and underground installation secured to an underground water lead conduit ii in any suitable manner as 10 by the screw threads shown and whose port 52 is closed by the pivoted swinging cover it which is substantially flush with the surface area it when the swinging cover is closed as best shown in Figure 1.

This water outlet is provided with a plurality of spaced inwardly radially projecting lugs v and has a resilient annular collar it of rubber or the like disposed within an annular recess ll circumscribing its port l2 and spaced from the lugs it. A valve comprising a pair of discs l8, l9 respectively of metal and of some resilient ma terial such as rubber or the like are disposed within the vertical bore IQ of the water outlet and are secured transversely and medially of a reciprocable plunger 26 whose lower end is adapted to reciprocate in the bore 2! of the collar 22 which forms a bearing for the plunger. A coiled expansion spring 23 embracing the lower end of the plunger and interposed between the 001- lar 22 and disc it normally maintains the resilient disc element is against the valve seat 26 to thus close the valve,

A sprinkler head 25 provided at its upper end with a plurality of conventional laterally disposed conduits 26 is connected to a tubular base member 21 whose lower end is provided with a resilient collar 28 1m within an annular recess 28. The lower end of the base member 2'5 has a plurality of spaced outwardly radially projecting lugs 30 which interlockingly register with the lugs l5 0! the water outlet It adapting the sprinkler head 25 tobe rotatably detachably coupled axially in aligned communicating relation with the water outlet ill and with the two re- 46 silient collars I6, 28 in compressed leak-proof contact as best shown in Figures 6 and 7. The annular recesses Ill and 29 of the water outlet and sprinkler head are formed by inwardly projecting annular walls and the resilient washer It is interlocked with the upper wall of the annular recess ll while the resilient collar 28 is interlocked with the lower wall of the reces 29. The annular recess of the sprinkler head is arranged in substantially the some horizontal plane as as the lugs of the sprinkler head. The lower wall of the annular recess ll of the water outlet constitutes a valve seat for the valve which operates between the valve seat and the guide formed by the fixed collar 22.

A cam. element 3| operatively associated with the head of the plunger 20 and disposed within the bore of the base member of the sprinkler head 25 is rigidly secured medially of the shaft 32 rotatable in its bearings 33, 3t and a manually operable lever 35 is secured to the outwardly projecting end of the shaft 32 for effecting rotation of the shaft.

As heretofore suggested, the surface area which it is desired to water, is provided with a plurality oi. spaced water outlets H) which are connected to underground conduits II as indicated in Figure 4. The valves of these spaced water outlets Ill are normally closed and when it is desired to water the area surrounding a particular water outlet, the sprinkler head 25 is detachably secured thereto as heretofore described. By the manual projecting internal lugs, a sprinkler head having a plurality of spaced radially projecting external lugs interlockingly registering with said other lugs and adapting the sprinkler head to be detachably axially coupled with the water outlet, a resilient collar carried by the sprinkler head and projecting below the lugs thereof, a resilient washer located within the water outlet and cooperating with the resilient collar to form a water-tight joint, means carried by the water outlet ,for interlocking the resilient washer with the water outlet, a portion of said means forming i a valve seat, a valve within the water outlet cooperating with the said valve seat, and valve operating means carried by the sprinkler head.

2. In a structure of the class described, a water outlet having a plurality of spaced radially projecting internal lugs, a sprinkler head having a plurality of spaced radially projecting external lugs interlockingly registering with said other lugs and adapting the sprinkler head to be detachably axially coupled with the water outlet, a resilient collar carried by the sprinkler head and projecting below the lugs thereof, a resilient washer located within the water outlet and cooperating with the resilient collar to form a water-tight joint, means carried by the water outlet for interlocking the resilient washer with the water outlet, said means including a lower annular wall forming a valve seat below the washer, a valve within the water outlet cooperating with the said valve seat, and valve operating means carried by the sprinkler head.

3. In a structure of the class described, a water outlet having a plurality of spaced radially projectinginternal lugs, a sprinkler head having a plurality'of spaced radially projecting external lugs interlockingly registering with said other lugs and adapting the sprinkler head to be detachably axially coupled with the water outlet, a

resilient collar carried by the sprinkler head and projecting below the lugs thereof, a resilient washer located within the water outlet and cooperating with the resilient collar to form a water-tight joint, means carried by the wateroutlet for interlocking the resilient washer with the water outlet, a portion of said means forming a, valve seat, a fixed guide located below and in spaced relation with the valve seat, a plunger slidable in the fixed guide and extending through the resilient washer and the resilient collar, a valve carried by the plunger and operating between the guide and the valve seat to cooperate with the latter, and valve operating means carried by the sprinkler head.
